A PTR (pointer) record maps an IP address to the domain name. It’s often called a "reverse DNS entry" because it converts an IP address to a name.
PTR records are mostly used as a security and anti-spam measure, to verify that a mail server address is allowed to send an email to a particular hostname. The reverse DNS entry checks if a server name is indeed associated with an IP address from where the connection was initiated.
In order to set up a reverse DNS entry that will connect an IP address to your domain (e.g., 127.0.0.1 should be mapped to yourdomain.com), you will need to contact your IP address provider to create a PTR record for the IP address.
Please keep in mind that PTR records are supported on our VPS and dedicated servers only
. Still, it is also possible to create the PTR record on Shared and Reseller packages if you have a dedicated IP address. For that, reach out to us via Live Chat
so that we can set the required PTR record.
